{Rishi T, Apu V, Rajagopal CV, Radhakrishnan CV} {Navigating common challenges in manuscript submission: Insights for authors using Elsarticle and \acro{CAS} packages} { The Elsarticle (\texttt{elsarticle.cls}) and \acro{CAS} (\texttt{cas-sc.cls} and \texttt{cas-dc.cls}) packages are Elsevier's recommended \LaTeX{} class files for manuscript submissions to their journals. Despite the availability of comprehensive documentation, authors unfamiliar with \LaTeX{} or those who overlook the guidelines often encounter issues during manuscript preparation. These issues can lead to extensive email correspondence and submission errors, such as incorrect metadata involving email addresses and corresponding author details. This paper aims to catalog these common pitfalls and offer practical solutions to streamline the submission process for authors. }
